Acute haemodynamic effects of urapidil in patients with chronic left ventricular failure 总被引:11,自引:0,他引:11
Summary Urapidil, a new alpha1-adrenoceptor blocking drug, has been shown to be effective in the treatment of hypertension. Ten normotensive patients with severe congestive heart failure were given Urapidil 25 mg i.v. twice in 15 min and the haemodynamic effects were measured.There was a significant fall in systolic blood pressure (–16%), mean blood pressure (–13%), left ventricular end-diastolic pressure (–38%), mean pulmonary artery pressure (–31%) and wedge pressure (–40%). Total peripheral resistance fell by 25%, whereas pulmonary arteriolar resistance did not change significantly. Cardiac output increased by 22%.The increase in cardiac output with decreasing peripheral resistance and LV pressures suggests that urapidil may be useful in the therapy of congestive heart failure. 相似文献

Methods: We investigated the pharmacokinetics of quinine (Qn) following administration of a single oral dose of 600 mg Qn sulphate in six male Thai patients with a moderate degree of chronic renal failure (CRF), and six male Thai subjects with normal renal function.
Results: The drug was well tolerated in both groups of subjects; no major adverse reactions were observed. A marked alteration in the pharmacokinetics of Qn was found in patients with CRF compared to healthy subjects; there were six signifiicant changes in the pharmacokinetic parameters. Absorption was delayed, but increased in CRF (tmax 4.5 vs 1.6 h, Cmax 6.17 vs 3.45 g·ml–1). Total clearance was significantly reduced 0.94 vs 2.84 ml·min–1·kg–1, whereas Vz/f remained unchanged (1.82 vs 2.78 1·kg–1). This resulted in the increased values of AUC and prolongation of the t1/2z and MRT in the patients (AUC 181.5 vs 61.8 g·min–1·ml–1, t1/2z 26 vs 9.7 h, MRT 36.4 vs 11.3 h). Median concentrations of plasma unbound fraction of Qn collected at 4 h after drug administration in patients and healthy subjects were 7.3 vs 9.8%, respectively. 相似文献

Summary Nicardipine is a new slow channel calcium blocker. It has been shown to be effective in the treatment of hypertension and angina pectoris. Nine patients with mild to moderate left ventricular failure were given intravenous infusions of nicardipine and the haemodynamic effects measured. In patients receiving 20 mg of nicardipine, mean cardiac index rose to a peak 1.8 l·min–1·m–2 (64%) above the preinfusion level, stroke volume index rose by 12 ml·m–2 (35%) and heart rate rose by 16 beats·min–1 (20%). There was a significant fall in systemic vascular resistance of 50% manifested by a reduction of 22 mm Hg in systolic blood pressure (18%) and 18 mm Hg in diastolic blood pressure (22%). Pulmonary vascular resistance fell by 45%. Mean pulmonary artery pressure and capillary wedge pressure did not change significantly. This study suggests that concomitant mild to moderate left ventricular failure is not a contra-indication to nicardipine therapy in patients with angina. 相似文献

Summary The study was designed to follow the haemodynamic effects and pharmacokinetics under steady-state conditions of three different doses of urapidil infused continuously. Nine male hypertensive patients received three randomly assigned intravenous infusions of 32.5, 65 and 130 mg urapidil, over 14 h during 6 consecutive days, in a change-over fashion. Blood pressure and heart rate were measured over a period of 28 h after the infusion began and were compared with a reference profile obtained prior to the treatment periods. Urapidil and its main metabolite, parahydroxylated urapidil, were also determined for 28 h after the infusion began using HPLC. The 32.5 mg dose of urapidil caused a maximum decrease in systolic blood pressure of 33±8 mmHg, the 65 mg dose a maximum decrease of 39±12 mmHg and the 130 mg dose a maximum decrease of 50±12 mmHg. The 32.5 and 65 mg doses resulted in similar serum urapidil concentrations, with maximum levels in the 100 to 200 ng/ml range, and the 130 mg dose caused a maximum level approximately four times that achieved with the 32.5 mg dose. The serum concentration of parahydroxy urapidil was proportional to the corresponding dose of urapidil. Four patients reported mild headache, fatigue, weakness, pressure in the head, perspiration and orthostatic dysregulation. The side-effects were probably drug related but required no specific therapy. In summary, the 32.5 mg dose of urapidil resulted in a pronounced decrease in blood pressure. The average pressure reduction over the 14-h infusion period showed further dose-dependent increases after the 65 and 130 mg doses. In severe hypertension, the 130 mg dose can be employed, since it does result in a further, significantly larger decrease in blood pressure. 相似文献

Summary Lisinopril (MK521), a lysine analogue of enalaprilic acid, the bioactive metabolite of enalapril, has a longer half-life than enalaprilic acid, and is excreted unchanged in the urine. Its kinetic profile and antihypertensive and hormonal effects have been investigated in an open study in 3 groups each of 6 hypertensive patients, with normal, moderate and severe impairment of renal function. Serum drug level, blood pressure, converting enzyme activity (CEA), plasma renin activity (PRA), aldosterone concentration (PAC), and serum potassium and creatinine were measured during 1 week following a single oral dose and subsequently following 8 daily doses of 5 mg lisinopril. Accumulation of lisinopril was found in the severe renal failure group. CEA was suppressed to less than 10% of its initial value from 4 to 24 h after the initial dose in all three groups, and the suppression was more marked and lasted longer in patients with severe renal failure. An inverse correlation was found in all patients between log serum lisinopril concentration and log CEA. Lisinopril lowered blood pressure in all three groups over 24 h. PRA rose and PAC fell similarly in the groups. Serum potassium increased in the renal failure groups and creatinine remained unchanged in all groups.Thus, when lisinopril 5 mg is given daily to patients with severe renal failure it may accumulate. The high serum lisinopril concentration does not cause an excessive antihypertensive effect. In patients with severe renal failure, adjustment of the dose or the dosing frequency to the degree of renal failure is recommended to avoid administration of doses in excess of those required to achieve adequate inhibition of converting enzyme. 相似文献
